Here is Steve's Official correction of ITL pg 25 :
JOBS. Clarification: Magic items (except Charms) do NOT help on the job-risk roll. Omission (may have resulted from my own error - whatever the source, it's important to play balance): " . . . give him enough experience points to raise one attribute, or 1,000 experience points, whichever is less."
This was originally printed in Space Gamer #29 July 1980. This is also available here:

add: In essence, there was never a give-away as a result of Jobs rolls after the first few attribute gains.
